GEORGE HOVVLETT DAVIS, OF BROOKLYN, NEV YORK.

STENClL-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 703,388, dated July 1,1902.

Serial No. 56,267. (No model.)

To @ZZ whom, it may concern:

Be it known that I, GEORGE HowLE'rT DAVIS, a citizen of the UnitedStates, and a resident of Brooklyn, in the county of Kings and State ofNew York, have invented a certain new and useful Stencil-Printin gMachine, of which the following is a specification.

My present invention relates to improvements in stencil-printingmachines, and more particularly to machines adapted for print. ingexpression characters, letters, or marks upon perforated music-sheetssuch as are employed to operate self-playing musical instruments, theimpression being made through the medium of a stencil-sheet having saidcharacters cut therethrough.

It is well known in the art that perforated music-sheets are now usuallyprovided with appropriate expression characters to denotewhen certainstops or expression-pedals are to be operated or when the speed deviceis to be actuated, and it is the purpose of the presont invention toprovide a machine for printing said expression characters or marks uponthe music-sheets.

It is the obj ect of my said invention to provide a simple andinexpensive stencil-printing machine oi' the class described and toprovide means whereby the printed music-sheet is given an opportunity tobecome dry before Briefly and broadly stated, the invention comprisessupply-rolls for the stencil-sheet,

and music-sheet to be printed, suitableinking mechanism, and an endlessconveyer belt or web,to which the said sheets are attachedIand by whichtheyare carried over Aidler-'pulleys through a given space, so as toallow theprinted music-sheet to dry before it is rewoun'd upon itsreceiving-roll.

Further, the invention comprises the novel features of construction andnew combinations and arrangements of parts hereinafter described andthen more definitely pointed out inthe claims which conclude thisspeciication.

Referring to the drawings, Figure 1 is a perspective view of a machineconstructed in accordance with my invention. Fig. 2 is a longitudinalsectional view of the same. Fig. 3

is a detail sectional View of a portion of the Vsaid gears.

-rnediate ink feeding or distributing rollers S 9, and animpression-roller 10', said rollers being in frictional contact and onejournaled above the other'. An ink-trough 12 lies directly below theink-supply roller and is supported by arms 13, which are attached to theside standards at let, as indicated.

At the extreme frontof the two side standards-is journaled an upperpower-shaft 15,

carrying-a conveyer-belt-driving roller 16, and below this shaft isjournaled asecond or lower power-shaft 17, having 'a doublegroovedpulley 18 at one Iend and a gear- 'wheel 19 at its opposite end, saidgear-wheel meshing with a similar gear 20,1ixed to the upperpower-shaft, the latter-named shaft being also provided with adrive-pulley 21, over which passes a power-belt 22 to drive`The-printing stencil-sheet'23Y is carried by a supply-roller 24,whichis journaled in bearings 25 on the side standards close to thebaseboard 1, said roller havingashaft extension 26 at one end, uponwhich is fixed a pulley 27, andover this pulley is" passed a cross-belt28, which receives its power from the pulley 18 on the lower power-shaft17. The musicsheet- 29 to be printed is mounted upon a roller '30, journaled in' bearings at the front of the side standards,as shown, saidmusic-sheet, together with the printing stencil-sheet, being passedbetween the inking-roller 9 and irnpression-roller 10, itibein'gunderstood that the printing-stencil is located below the music-sheetand theinkforced through the perforations therein upon the music-sheet.The ink-distributing roller 8 is provided with a pulley 31, over whichpasses a belt 32 from the double-grooved pulley 18, whereby said vIsdistributing-rollers, as well as the ink-supplying roller 7, arerevolved.

The reference-numeral 33 designates an endless conveyer belt or web,which is of considerable length and which passes over suitableidler-pulleys 34, located at desired points throughout the room, andsaid belt or web passes over and is driven by means of thedriving-roller 16. This conveyer belt or web 33 is provided at someappropriate point with a clamp consisting of a transverse plate 35,which maybe tightly pressed upon the .web by means of thumb-nuts 36,tapped upon screws 37, said screws being secured to the web and passedthrough openings in the plate 35. It will now be understood that byplacing the ends of the stencil-sheet and musicsheet between theclamping-plate and-screwing the thumb-nuts tightly against said platethe said sheets will be secured to the web, so that if the web is movedor advanced the sheets must likewise be advanced and moved therewith.

Projecting upward from opposite sides of the side standards, between thestencil-roll and music-sheet roll, are two arms 38, each carrying aspindle-bearing 39, into which may be placed a music-roller to receivethe musicv sheet after it has been printed and its end brought around bythe conveyer-web, so as to be attached to said roller. One of saidspindle-bearings is provided with a pulley 40, that receives motionthrough the belt 28, which is shifted from the pulley 27 after thestencil-sheet has been entirely unwound from the roll 24, whereby thesheet-receiving roll is rotated to wind the printed sheet thereon.

In operation the stencil-sheet and musicsheet are mounted upon theirrespective rolls 24 and 30 and their ends passed between the ink-supplyroller 9 and impression-roller l0 and then secured by the clamping-plate35 to the endless conveyer belt or web The machine being now set inoperation, the conveyer belt or web drags the two sheets 23 and 29forward between the inking and impression rollers, whereby ink is forcedthrough the opening in the stencil-sheet and deposited upon themusic-sheet, as will be understood. The conveyer belt or web is slightlylonger than the longest music-sheet to be printed, which is probablythirty feet, more or less, and when the belt or web has made onecomplete circuit until the forward ends of the stencil-sheet andmusic-sheet pass over idler-pulley 34L they are released from theclamping device on the web and the music- @sheet is wound upon areceiving-roller, (not shown,) which is mounted in the bearings 39 ofthe two arms 38, said roller being revolved through the belt 28, whichhas now been placed over pulley 40. The stencil-sheet 23 fore, it beingunderstood that these rollers 30 are removably attached in theirbearings in any suitable manner so that they may be 'attached andremoved at pleasure. The two sheets are now attached tothe conveyer webor belt by the clamping device and drawn forward, as heretoforeexplained with respect to the first operation. These operations arecarried on continually until all the sheets are printed, and then thestencil-sheet may be wound up upon its roller 24, motion being impartedto the latter by means of the belt 28, which is now shifted back on thepulley 27 from the pulley 40.

Vhat I claim isl.. In a stencil-printing machine, the combination withan inking-roller and an impression-roller, of a stencil-sheet adapted tobe passed between said rollers, a conveyer belt or web, and means forattaching the stencilsheet to said belt or web, for the purposespecified.
